If a call connects but you or the other person cannot hear audio, start with the checks for your device.
Desktop app or browser
Follow Desktop App Sound Settings to select your headset and test your microphone and speakers.
If microphone access is denied, follow Microphone Permissions to reset and allow access.
Check that your computer is not muted and your headset is selected for both Input (microphone) and Output (speakers). In Windows, you may need to select Chrome / Edge’s audio devices in Volume Mixer. See Sound Settings (Windows).
If you use a Bluetooth headset, disconnect it from your phone while testing calls on your computer.
Mobile app (iPhone and Android)
Follow the mobile sections of Microphone Permissions to enable microphone access and check your phone’s volume and Bluetooth connection.
Still having trouble?
Try a test call with another contact to check whether the issue affects one person or everyone. If poor audio affects only one contact, their signal may be the cause.
On mobile, try switching between Wi-Fi and mobile data, then make another test call.
If the problem continues, contact us via chat with an example call’s date and time, the device you’re using, and whether you’re on Wi-Fi or mobile data.
